如何解决我得到的多个“不能对非静态字段进行静态引用”错误？[副本]

Question

我知道这个问题在这个网站上被问了很多次，但给出的答案似乎对我没有帮助。我对爪哇很陌生。

import javax.swing.JOptionPane;

public class Lab10 {

    String species, color, injuries, name, wiput, liput, locationFound, oiput;
    char gender;
    float weight, length;
    boolean hasShots, needsShots;
    int tagNumber, cageNumber, outcome;

    public static void main(String[] args) {
        strayAnimal(species, color, weight, length, injuries, locationFound, name);

    }

    public static void strayAnimal(String species, String color, float weight, float length, String injuries, String locationFound, String name) {
        species = JOptionPane.showInputDialog("Please enter the species of the animal: ");
        color = JOptionPane.showInputDialog("Please enter the color of the animal: ");
        wiput = JOptionPane.showInputDialog("Please enter the weight of the animal");
        weight = Float.parseFloat(wiput);
        liput = JOptionPane.showInputDialog("Please enter the lenght of the animal: ");
        length = Float.parseFloat(liput);
        locationFound = JOptionPane.showInputDialog("Please enter the location the animal was found(City, County, State): ");
        injuries = JOptionPane.showInputDialog("Please enter the injuries the animal has seperated with commas: ");

    }
    //public static char strayAnimal() {

    //}
    public static void setOutcome(int outcome) {
        oiput = JOptionPane.showInputDialog("Please enter a '0' if the animal has or will be terminated or a '1' if the animal has been saved: ");
        outcome = Integer.parseInt(oiput);
    }
    public void giveShots() {
        boolean giveShots;
        if (giveShots = true) {

        }
    }
    public static void needShots() {
        boolean needShots;
    }
}

您有一个静态方法，例如setoutput，它希望访问非静态变量，如output。那是不允许的。必须使变量output为静态或方法为非静态。
